A few comments from the many satisfied customers using the G4TPH Portable Magloops:
G4TPH HAS A GREAT PRODUCT !!!!!
I had used loop antennas before without much success. I sold my other commercial unit for another purchase. When investigating another one I chose the G4TPH for cost as much as anyting else.
I ordered the antenna over the intenet.
When I got the confirmation found I had ordered the wrong unit. Tom gladly changed the order and sent me the other unit. I had paid via Pay Pal as a guest. He sent the upgrade at no charge.
It arrived in 7 days from order and was packed nicely.
It was quickly assembled and was suspended from a light fixture in the "shack". You HAVE TO GET IT ON THE AIR !
One contact to W.Va. and not much luck the first day or the second.
AND THEN !!!! I heard SM5CAK finishing a QSO on 15 meters CW.
HE CAME BACK FIRST CALL. We had a nice chat and he sent me a 559...
AMAZING.....4600 miles on 30 WATTS from INSIDE THE SHACK!!!
I will do another report when camping season comes around but my first impressions are FINE BUSINESS TOM.
Given how this antenna works as it does from inside the house ...I can only imagine how well it will work in the great outdoors!
Thanks very much Tom for your product.
Tom, just got back from a week of depositions in New Orleans. Your small package was waiting. I put it together pretty quickly with considerable scepticism, but I was AMAZED at the results. I slapped my MFJ Analyzer on it and could bring it down to almost 1:1 on all bands with your capacitor, so your 1.2/1 is very conservative. Then, I called my cousin, KE9IK in Illinois and set up a QSO. He said that I was 58 to 59 from Houston. I am attaching a photo of the loop using 10 bars instead of 12 dangling off my closet door on the second story of our house. No DX yet and frankly I don't have any time for it, but your loop does work and work well. Perhaps it will work out well in my business travel as most hotels are hermetically sealed these days. Congrats on an excellent product. Feel free to use my endorsement and photo in any ad.
"i have one of your ml40 Magloops and i would like to take this opportunity to tell any prospective buyers that i have worked most of europe, russia, east and west coasts of north america and a few countries in south america with this antenna indoors in a first floor bedroom! this was exclusively on psk mode and only on 20w! i have no connection to the maker of the antenna (G4TPH). just thought i'd pass on my experiences of using this antenna."
thanks Ian G1WEV
Hi, Just to add , I have a ML-40 and i had it hanging on the bedroom doom just to try it the first time and i worked Moscow, France , Spain, and i got a contact in to london all on my ft817 running on its battery 2.5 watts ,From Newcastle upon tyne , There's nothing more to say is there !... 8293keith
I have now had time to test the loop antenna, and on 20m with 15W I worked Italy, Spain on PSK31
Amazing result considering that the loop is indoors around the window.Much stronger sigs and less noise than my verticals.Can I run 20W with this antenna? What do you think the max it can handle would be ? Also the clarity of SSB is the best so far.I will let you know more shortly. Well done for a great solution to no antenna space .
